I've been doing some googling, and the rpc_pipefs is a feature/function/product of nfs4. It's used for communicating between nfs4 servers and clients and doesn't contain anything you need to back up, it's all dynamically generated as part of client/server interactions. I'd just put that --one-file-system parameter back on your tar command and ignore the whole tree. I wouldn't attempt restoring any of that data into a client filesystem, you'd just muck up your existing nfs mounts.

There is no evidence of that shown by an ls -l being executed anyplace in that tree. I'll do a similar df check on the other failure points. When I am fully awake. No one would accuse me of that at 5am local. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
